The use of a p‐type inorganic semiconductor to form a nanorod scaffold within a polymer‐fullerene bulk heterojunction solar cell is reported. The performance of this cell is compared to those made of the commonly used n‐type scaffold of ZnO, which has been reported many times in the literature. The scaffold is designed to improve charge‐carrier collection by increased mobility in thicker samples. Observations show that generally the device performance shows a negative correlation to nanorod length. By using CuSCN as a p‐type inorganic scaffold, a very similar trend is observed.
